Needle coke with low electrical resistance, strong shock resistance and good anti-oxidation ability has been widely used in ultra high power graphite electrode, nuclear reactor deceleration materials and LIB anode materials. There are coal-based needle coke and oil-based needle coke.

From 2006 to 2014, the global needle coke capacity was expanded slowly at 3.6%, mainly because of the capacity expansion control by the industry's giants to maintain high profit margins. By contrast, the global demand for needle coke is growing rapidly, making the demand-supply gap increase year by year. In 2014, the demand rose 62.9% from a year earlier, to 290 kilotons.

The Chinese needle coke industry began in the 1970s and '80s, however, the capacity has surged in recent years along with the technical breakthrough. In 2006-2014, China's needle coke capacity increased from 60 kilotons to 260 kilotons, at a compound annual growth rate of 20.1%. In 2015, as the Huahang Energy's needle coke project went into operation, China's needle coke capacity has reached 280 kilotons.

Needle coke capacity can't meet the domestic market demand despite the increase year by year e.g. the demand-supply gap was 72 kilotons in 2014, China needs to import needle coke from the United States, Japan, Britain and other countries every year. In 2014, China recorded an import volume of 47 kilotons.

Global needle coke production enterprises are mainly concentrated in the United States, Japan and China. The US-based ConocoPhillips as the world's largest oil-based needle coke producer registers capacity of about 370 kt/a in 2015; the Japan-based C-Chem as the world's largest coal-based needle coke producer registers capacity of 170 kt/a in 2015. Chinese companies started relatively late, but in order to enhance the international competitiveness, they all have been increasing investment in needle coke projects over the years.

The total capacity of Sinosteel Anshan Research Institute of Thermo-Energy Co., Ltd. tops China by surpassing Shanxi Hongte Coal Chemical Industry Co., Ltd. after it adjusted the 80 kt/a needle coke project phase II capacity from 40 kt/a to 120 kt/a in 2012. In January 2015, the company's coal-based needle coke industrialization project passed the MOST (Ministry of Science and Technology) review and was officially included in the National Torch Program projects.

Jinzhou Coal and Coke Group started the construction of 100 kt/a coal-based needle coke project in 2010, divided into two phases. The first phase (50 kt/a) was completed in 2013, and the second phase began bidding in April 2015.
